This kit contains 4 rubber vibration isolators, which are what essentially transfer the power from the motor to the scrub deck on our 20" and 28" CleanFreak dry strip machine.
The 20" model will take 1 pack (4 isolators) per deck, and the 28" model will take 2 packs (8 isolators). With heavy use these isolators will wear out, which is why we recommend replacing them after extended periods of use. Replacing those old, worn out isolators, will make your square scrubber feel like new again.
Other accessories that we stock for this machine are the dust control kit, additional 22 lb. weight, and our square scrub, buff & strip pads.
